Bitdefender In Windows Task Switcher

Ever since I installed bitdefender, which I like very much, I am getting what appears to be one or more otherwise hidden windows in my taskswitcher... I can't actually go to those windows as they don't exist, but they constantly show up in the default windows taskswitcher.


What are they and how can I get rid of them?
